Transmitting the power from the motor to the wheel, the primary transmission shaft pulley of the Sur Ron Light Bee is an essential component of your bike.The pulley wears off over time and when its teeth are worn or damaged, it's time for a change.A worn pulley increases the risk of belt slippage, rupture and premature wear. A broken belt means having to push the bike home, not exactly the coolest memory you'd want with your Light Bee ride!
